  1. I have a 9mm volcano top if you are still looking £30 posted.
  2. Before jumping in why not come along to one of our meetings, search for PADAS. We are based in the Jeremiah Horrocks observatory, Moor Park, Preston
  3. My TAL 100R has beautiful purple coatings, now used as a TAL/PST Ha modded scope.
  4. Surely by the time it gets to the ep all harmful energy should have been removed? Edit - sorry should have thought about this - solar projection lol
  5. Preferably in the Lancashire / West Yorkshire area so I can collect. Thanks Nigel
  6. In Preston the dome appears to have a blue tinge nowadays, not good.
  7. Here is the original article collimation_with_a_Barlowed_Laser-1.pdf
  8. Agreed, but not accurate enough using the in built screen
  9. I recently found an interesting Sky and Telescope article for using a barlowed laser to collimate newtonians, this was the photograph used in the article. The only problem is that in reality the projection screen is that high up the draw tube its only visible using a compact mirror (photo is of our society's Skywatcher 200p dob) I had already fabricated a screen for the bottom of the barlow but decided to abandon this on favour of an alternative. My final solution was to make a card screen which slips over the end of the focuser tube Initial impressions are that it works well.
  10. A quick review of UKABS just now shows that out of the 1376 adverts, 236 are sold and 28 are withdrawn.
